The many options for managing brine, a term for saline wastewater from industrial processes, fall under two categories: brine treatment and brine disposal. Brine treatment involves desalinating the brine for reuse and producing a concentrated brine (lower liquid waste volume), or residual solids (zero liquid discharge).
Treatment and reduction solutions
Our innovative brine management solutions minimize volume, reduce your disposal costs, and maximize freshwater recovery.

Treatment & Disposal
Brine management options may include treatment followed by disposal. Treatment desalinates brine and produces a more concentrated, lower volume fluid or solids which are easier to transport or dispose of. Disposal involves discharging brine to sewers, surface water, injection wells, or sending it to environmental service providers.
Saltworks’ brine management experts can help you to understand your treatment and disposal options, including discharge regulations and economics for your process.
Understand Brine Chemistry
Water chemistry analysis is essential to understand key brine management factors such as salinity, scaling potential and content of metals or other contaminants. Our team can manage this analysis for you, perform feasibility testing, and develop a treatment solution that meets regulatory requirements, maximizes plant performance and up-time, and minimizes maintenance costs.
Maximize Membrane RecoveryEffective brine treatment firstly requires maximizing recovery of lower cost membrane systems—such as reverse osmosis (RO)—before additional treatment or disposal. The next step is comparing disposal options against thermal treatment, to decide whether to further concentrate your brine or treat it down to solids. We supply extreme recovery membrane brine concentrators comprised of our XtremeRO products coupled with our BrineRefine precision chemical softening systems.
Minimal & Zero Liquid Discharge
Maximized your membrane recovery but need further brine volume reduction? Let us help you to de-risk your minimal or zero liquid discharge needs with expert information on preventing scale, solids handling and disposal, and overall cost of ownership. We also supply modular, fully packaged industrial evaporator-crystallizers for ultra-reliable thermal MLD and ZLD treatment, such as our SaltMaker product Family.

Before investing in an industrial evaporator for your water treatment applications, lower your risks by asking any vendor the following five questions that cover key topics such as brine disposal, scale prevention, and cost of ownership.
Treating RO brine should be approached from two directions. First, maximize the recovery of lower cost membrane systems to minimize the volume for later steps. Second, weigh brine disposal options against thermal treatment technology to determine whether you need to concentrate your brine or treat it down to solids.
RO recovery and RO brine concentration is limited by osmotic pressures or membrane scaling; both limits have been increased by new technology. A series of techniques described in this document can be used to delay or mitigate scale, but in many cases only chemical softening truly removes the risk.
